Question

MCQ (100)
053. The area of his hysteresis loss is a measure
of
(A) Permittivity
(B) Permeance
(C) Energy loss per cycle
(D) Magnetic flux​

Answer 1

Answer:

c

Explanation:

Area enclosed by a hysteresis loop is a measure of energy loss per cycle of the paramagnetic materials used for electromagnets and transformer.

Answer 2

The area of his hysteresis loss is a measure of (c) Energy loss per cycle.

• Hysteresis loss is the amount of heat energy loss during the magnetization and demagnetization of the core of magnet caused by the current flow.
• The hysteresis loss is generally plotted in a curve between magnetic flux density (B) and the magnetizing force (H).
• It is a closed loop of B-H graph.  
• Smaller the area enclosed by the hysteresis curve, lesser the heat loss.
• There can be two types of hysteresis loss.
